# @remotion/media-parser

:::warning
[We are phasing out Media Parser and are moving to Mediabunny](/blog/mediabunny)!

<br />
<br />

This is a package that parses video and audio files to extract metadata and samples.

Design goals:

- [Support all major containers](/docs/media-parser/format-support): `.mp4`, `.mov`, `.webm`, `.mkv`, `.avi`, `.m3u8`, `.ts`, `.mp3`, `.wav`, `.aac`, `.m4a` and `.flac`.
- [Easily get various information](/docs/media-parser/fields) from multimedia files
- [Work in the browser, Node.js and Bun](/docs/media-parser/runtime-support)
- [Satisfy your query with minimal fetching](/docs/media-parser/fast-and-slow)
- [Functional TypeScript API](/docs/media-parser/parse-media)
- [Be useful when passing unsupported media](/docs/media-parser/foreign-file-types)
- [Allow decoding video frames and audio samples using WebCodecs](/docs/media-parser/webcodecs)
- [Pausable, resumable and cancellable](/docs/media-parser/pause-resume-abort)
- [Be able to seek to a different position in a media file](/docs/media-parser/seeking)
- No dependencies

## Hello World

Get metadata from a video file - [over 20 different fields are supported.](/docs/media-parser/fields)

```tsx twoslash title="Get the duration and codec of a video"
import {parseMedia} from '@remotion/media-parser';

const {durationInSeconds, videoCodec} = await parseMedia({
  src: 'https://remotion.media/video.mp4',
  fields: {
    durationInSeconds: true,
    videoCodec: true,
  },
});

console.log(durationInSeconds); // 5.056;
console.log(videoCodec); // 'h264';
```

Extract samples from a video file - [supports WebCodecs](/docs/media-parser/webcodecs).

```tsx twoslash title="Extract samples from a video"
import {parseMedia} from '@remotion/media-parser';

await parseMedia({
  src: 'https://remotion.media/video.mp4',
  onVideoTrack: ({track}) => {
    // Get information about the
    console.log(track.width);
    console.log(track.height);
    return (sample) => {
      // Retrieve samples as they are extracted
      console.log(sample.timestamp); // 0
      console.log(sample.data); // Uint8Array(12345)
    };
  },
});
```

<details>
<summary>What are samples?</summary>

Samples contain audio or video data - but they are compressed using codecs like AAC for audio or H.264 for video.  
You can turn audio samples into a waveform and video samples into images by decoding them.

## How does this compare to FFmpeg?

- Media Parser specializes for JavaScript and on the web.  
  It is designed to embrace the language and make use of the APIs that JavaScript has to offer.
- Unlike FFmpeg, Remotion Media Parser does not have functionality for decoding and encoding – it only parses media files.  
  Instead, we hope you combine it with WebCodecs, the native API built into browsers.
- Media Parser has no command line interface and cannot be integrated into native applications.

## How does this compare to MP4Box.js?

MP4Box.js does a better job at parsing the ISO Base Media Format (`.mp4`, `.m4a`, `.mov`) and supports reading more information from it.  
Remotion Media Parser supports more [container formats](/docs/media-parser/format-support), with the goal that it can handle arbitrary user-provided media files.
